You have to check out this picture of a miniature horse in a restaurant. OK, it’s probably staged, but the fact that you could even get an equine to do this just proves that my miniature horse fantasy was not so far-fetched. An Arizona House panel has approved miniature horses as service animals, falling into line with new-ish federal ADA regulations. Next question: Which size of miniature horse are we going with here? The American Miniature Horse Association's 34-inch model or the 34+-to-38-inch mini described by the American Miniature Horse Registry? Actually, the way I read the regulation, size doesn't matter, as long as the mini fits the activity.
